How to treat a jellyfish sting

If you friend has just been stung by a jellyfish it might be the rare occasion when they will be happy to have a golden shower!!

General Jellyfish Stings Treatment


  • Rinse the area with sea water.
  • Deactivate remaining cells with a vinegar rinse. If no vinegar is available use urine (preferably male urine as it's considered to be more sterile), apart from Box jellyfish and Irukandji stings.
  • Remove any remaining tentacles with a stick or similar – be careful not to touch them yourself.
  • Remove any remaining cells by dusting with flour and then carefully scraping them off. 
  • Manage any unconsciousness with a safe airway position.
  • CPR may be necessary for all stings if the person stops breathing and/or no longer has a pulse.

After all tentacle sections and stinging cells have gone:

  • Pain can be treated with a cold pack and/or a local anaesthetic such as a sunburn lotion or insect bite treatment that lists '...ocaine' as an ingredient.
  • If there is continued swelling, or itchiness, apply a light steroid cream e.g. Hydrocortisone eczema cream.
  • If muscle spasms persist see a doctor.


  • Do not scrub or rub the area.
  • Do not wash with fresh water.
  • Do not pour sun lotion or spirit-based liquid on the area.

All of theses will aggravate the stinging cells.

If you are stung by a box jellyfish, seek medical help immediately. While you are waiting for medical help, flood the area with vinegar and keep as still as possible.

If you are not close to medical care, soak the area and tentacles for 10 minutes or more, before attempting to remove them. If the sting is on the arms or legs, you can place a pressure dressing around the sting to help slow down the spread of the toxin. Be careful that you do not cut off circulation the remainder of the limb below the dressing must always remain pink.
